Topic: Error 451

Hi,

We are trying to send emails to nokia domain, but get an error. When I send same email from my other server, it works without any problem.


What could be the reason? Nokia mailserver is blacklisting my iredmail server?

Thanks
Richard

Looks like a greylist to me. Should be fine in a few minutes...
